IGCSE Physics Paper 1 Variant 1

[Micro961]

I just did it today.. How was it?

 

[MTH]

What did you answer on the question about fuse ??

 

[Ahmed GolD]

Was it the liquid is expanding or the molecules in the liquid are?
And was it 68 cm of mercury .

 

[MTH]

Do you mean the barometer question ?

 

[Micro961]

What did you answer on the question about fuse ??

which one??

Was it the liquid is expanding or the molecules in the liquid are?
And was it 68 cm of mercury .

-Liquid expanding
-Its 84 because pressure of gas =atmospheric pressure + difference in height

 

[Micro961]

Guys the question about two iron bars X and Y, what did you do?
and the question about the box and where u had to choose closed switch, resistor, capacitor etc..?

 

[Ahmed GolD]

which one??

-Liquid expanding
-Its 84 because pressure of gas =atmospheric pressure + difference in height

It can't be 84 because the gas pressure was lower

 

[phantom]

which one??

-Liquid expanding
-Its 84 because pressure of gas =atmospheric pressure + difference in height

Its 68, because atmospheric pressure was MORE than the Gas's

 

[MTH]

The one that ask which fuse should we use in the circuit that had TV and radio (I guess). The answers had 3 5 10 and 13

 

[Ahmed GolD]

So pressure=Atmospheric + difference in h
=76 cm. + (-8)
76-8=68

 

[aliiiiiiiiii]

easyyyyyy

 

[Manobilly]

Guys the question about two iron bars X and Y, what did you do?
and the question about the box and where u had to choose closed switch, resistor, capacitor etc..?

The two iron bars would be attracted!And its a constance resistor!

 

[Manobilly]

It was Alhumdullilah gud but some questions repeated from last years!

 

[MTH]

according to the dgh formula right ?

 

[Jspake]

The iron bars would be repelled.. there is always an opposition at the ends of the coil! I think so..

 

[Jspake]

Guys.. what was the answer to the potential divider question??

 

[Weirdal95]

It was 68 mercury,The potential divider was from 0-12v, and the rods would get attracted to the coil.
and I put constant resistor for the ''x'' thingy with the graph!but not sure if its right though...

 

[Yousif Mukkhtar]

It was 68 mercury,The potential divider was from 0-12v, and the rods would get attracted to the coil.

Yeah that is correct. Too bad I put 84!!!

But overall it was a great paper.

 

[Weirdal95]

Did you put constant resistor?

 

[Yousif Mukkhtar]

Did you put constant resistor?

That is correct.
